What makes you think a single "glyph" that represents one of these 3.4⏨38 items could possibly be sensibly distinguishable at any sort of glance (including long stares) from all the others? I have an idea for that: we can show the actual *digits* of some encoding of the 128-bit number. Then just inspecting for a different digit will do.there's no restirction that it be one character cell in size... rendered glyphs could be thousands of pixels wide...
Yes, but at that point it becomes a huge stretch to call it a "character". It becomes more like a "picture" or "graphic" or something. And even then, considering the tremendohunormous number of them we're dealing with, can we really be sure each one can be uniquely recognized as the one it's *supposed* to be, by everyone?
